I have all five gulpers now together in my 135g, I will be upgrading this summer to a 240g. I have two males and three females. Its funny watching how they all swim together, and all go nuts over food Their behavior in the group of reminds me of bowling, four of them sit at one and the fifth gulper swims from the other side of the tank and crashes into them. Seems like they all take turns doing it over and over lol
They each get one jumbo shrimp every other day. It only $6 for a bag of 35-40 shrimp, so its not that bad If I can find my old digital video camera I'll throw up a video. Its funny in the morning when the lights come one. They all scatter and swim around the tank.
